PRIORITY CLAIM

This application claims priority to U.S. Provisional Application, Ser. No. 63/128,637, filed on Dec. 21, 2021, entitled Systems and Methods For Active Cargo Carrier Mounting System, which is hereby incorporated by reference in its entirety for all purposes.

BACKGROUND OF THE INVENTION

Cargo carriers, also known as roof boxes, ski boxes, cargo boxes, roof top boxes, car toppers, or the like, are portable storage containers that can be secured to the top of an automobile on an as-needed basis. Such cargo carriers may be secured to structural elements, such as mounting brackets, roof racks, side rails, crossbars, or the like. These structural elements are typically integrated components that are permanently secured to the roof of the vehicle.

One problem encountered in the arts is that the roofs of the many different vehicle models vary significantly in shape, size and profile. Accordingly, some cargo carriers may only be suitable for a particular vehicle model. Universal cargo carriers are available, but their application may still be limited to a number of different vehicle models.

Many vehicles do not include permanently secured structural elements. Glass tops and/or glass sun roofs are becoming increasingly popular in the automotive industry. Further, there is a trend away from including permanently secured structural elements on new vehicles, especially sport cars. Accordingly, most commercially available cargo carriers are simply unsuitable for use in vehicles that do not have permanently secured structural elements.

Accordingly, in the arts of automobile cargo carriers, there is a need in the arts for an improved methods, apparatus, and systems for permanently or releasably securing a cargo carrier to the top of an automobile while maintaining the required safety standards and providing methods to prevent theft.

SUMMARY OF THE INVENTION

Embodiments of active cargo carrier mounting system secure a cargo carrier to a top surface of a vehicle using an outer seal secured to the rooftop of a vehicle, at least one vacuum pump controllably coupled to a microcontroller, a vacuum line fluidly coupled to the at least one vacuum pump, and a plurality of vacuum cups configured to secure the active cargo carrier mounting system to the rooftop of the vehicle.

DETAILED DESCRIPTION

FIG. 1 is a partially transparent top view of an active cargo carrier mounting system 100. In the non-limiting example embodiment, the active cargo carrier mounting system 100 is coupled to a cargo carrier 102. In some embodiments, suitable fasteners may be used to secure the cargo carrier to the active cargo carrier mounting system 100. Suitable fasteners may include snaps, buttons, straps, belts with buckles, hook and loop fasteners, zippers or the like. In other embodiments, the cargo carrier and the active cargo carrier mounting system 100 are fabricated as a unibody integrated system.

When the user wishes to use the cargo carrier, the active cargo carrier mounting system 100, in a preferred embodiment, may be permanently secured to the vehicle roof 104. Alternatively, the active cargo carrier mounting system 100 may be releasably secured to the vehicle roof. When the user is not using the cargo carrier, the active cargo carrier mounting system 100 is released from the vehicle roof 104 so that the active cargo carrier mounting system 100, preferably with an integrated cargo carrier, can be removed from the vehicle on command via a hand held device and/or an internal switch.

An unexpected advantage provided by embodiments of the active cargo carrier mounting system 100 is to improve safety in using cargo carriers and by providing antitheft protection. The vacuum cups 106 (interchangeably referred to herein as suction cups 106) of the active cargo carrier mounting system 100 provide a stronger securing means for securing the cargo carrier 102 than legacy securing means. Additionally, the active cargo carrier mounting system 100 is tamper resistant and cannot be easily removed by a thief.

The disclosed systems and methods for securing a cargo carrier to a vehicle roof 104 using the active cargo carrier mounting system 100 will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide examples of the various inventions described herein.

Returning to FIG. 1 , the active cargo carrier mounting system 100 comprises a microcontroller 108, one or more vacuum pumps 110, a battery 112, a vacuum line 114, a plurality of vacuum cups 106, a plurality of tee fittings 116, an outer seal 118, and at least one optional pressure sensor 120. Any suitable processor-based 108 may be used in the various embodiments.

In a preferred embodiment, each vacuum cup 106 is fluidly coupled to the vacuum line 114 using a tee fitting. A first end of the tee fitting 116 is fluidly coupled to a proximal point in the vacuum line. A second end of the tee fitting 116 is coupled to an inlet of a vacuum cup. A third end of the tee fitting 116 is fluidly coupled to a continuing portion of the vacuum line. The continuing portion of the vacuum line 114 is fluidly coupled to a next one of the plurality of vacuum cups 106 using a tee fitting. Accordingly, a plurality of vacuum cups 106 may be fluidly connected to the vacuum line 114 in a serial fashion or other manner. Other embodiments may couple the plurality of vacuum cups 106 to one or more vacuum lines using alternative fluid couplers.

In a preferred embodiment, an outer seal 118 forms a seal between a lower surface of the cargo carrier 102 and the vehicle roof. The outer seal 118 is a suitable semi-rigid or flexible foam-like material that generally conforms to the shape and size of the outer perimeter the active cargo carrier mounting system 100 and/or the cargo carrier. In a preferred embodiment, the outer seal 118 is made of neoprene, rubber, rubberized foam, or the like of a suitable thickness (height) that is sufficient to create a cavity between the lower surface of the cargo carrier 102 and the vehicle roof. Accordingly, the active cargo carrier mounting system 100 fits between the lower surface of the cargo carrier 102 and the vehicle roof, and is surrounded by the outer seal.

In a non-limiting example embodiment, a suitable adhesive may be used to secure the outer seal 118 to the cargo carrier 102 and/or the vehicle roof. In other embodiments, the seal 118 may be secured using other means, such as hardware. In a preferred embodiment, the outer seal 118 forms a continuous ring of material surrounding the active cargo carrier mounting system 100. In other embodiments, a non-continuous ring of material is used for the outer seal. Alternatively, or additionally, strips of material placed at selected locations may be used to form the outer seal.

In some embodiments, the outer seal 118 is not secured to either the lower surface of the cargo carrier 102 and the vehicle roof 104 or the vehicle roof. Rather, after the active cargo carrier mounting system 100 is placed in position over the vehicle roof, the outer seal 118 is placed on the vehicle roof 104 around the active cargo carrier mounting system 100. Then, the cargo carrier 102 is placed on the vehicle roof, resting on a top surface of the outer seal.

In the various embodiments, in response to actuation of the active cargo carrier mounting system 100, air is drawn out from the plurality of vacuum cups. The plurality of vacuum cups 106 partially collapse, decreasing their height as the vacuum within the vacuum cups 106 is created. Since the bottom of the cargo carrier 102 is secured to the active cargo carrier mounting system 100, the downward collapse of the vacuum cups 106 pulls the lower surface of the cargo carrier 102 downward. Accordingly, the outer seal 118 is compressed to form a frictional seal between the lower surface of the cargo carrier 102 and the vehicle roof. Since the vacuum cups 106 are within the cavity formed by the compressed seal, the vacuum cups 106 are protected from weather and moving air over the vehicle roof 104 as the vehicle is moving. That is, since the outer seal 118 is made of a flexible and air tight material such as neoprene or the like, the outer seal 118 serves to diffuse air away from the vacuum cups 106 to avoid disturbance to the vacuum cups 106 while the vehicle is moving. By protecting the seal of the vacuum cups 106 to the vehicle roof, power requirements on the vacuum pumps 110 may be decreased. Further, reliability may be increased to the leading edge vacuum cups 106 that may otherwise experience the greatest “lift” during vehicle movement.

In a preferred embodiment, the outer seal 118 is initially provided as a sheet of material that the user may cut to a desired shape and size. Alternatively, or additionally, a pre-cut outer seal 118 may be provided that is cut based on the dimensions of the active cargo carrier mounting system 100, the cargo carrier, and/or the user's vehicle model.

In practice, the user places the active cargo carrier mounting system 100 onto the vehicle roof 104 and adjusts the location of the plurality of vacuum cups 106 to a desired location on the vehicle roof. Next, the user actuates the active cargo carrier mounting system 100 to cause the controller to operate a vacuum pump 110 to create a vacuum within the vacuum line. The created vacuum then draws air from the underside of each vacuum cup 106 to create a vacuum. The generated vacuum then seals the vacuum cup 106 to the top surface of the vehicle roof 104 so long as the vacuum is maintained. Accordingly, the integrated cargo carrier of the active cargo carrier mounting system 100 is then secured to the vehicle roof.

Preferably, when the vehicle has a glass top, the plurality of vacuum cups 106 are located over the glass top. A relatively strong seal is created between each vacuum cup 106 (and the intervening outer seal) and the smooth glass surface of the vehicle's glass top. Alternatively, the plurality of vacuum cups 106 may be secured to a painted surface of a metal vehicle roof. Further, the active cargo carrier mounting system 100 can be used to secure a cargo carrier 102 to other surfaces of a vehicle, such as a vehicle trunk, side, or other surface.

The cargo carrier 102 may be a box-like structure configured to store items within the interior of the cargo carrier. Alternatively, the cargo carrier 102 may be a rack or other securing device that may be used to secure other objects of interest, such as bikes, surfboards, fishing equipment, golf clubs, tools, ladders, or the like, to the vehicle roof.

A preferred embodiment has two or more vacuum pumps. Multiple vacuum pumps 110 provide for reliability in the event of a single vacuum pump 110 failure. Also, multiple vacuum pumps 110 can be used together to create a stronger vacuum.

In an example embodiment, a pressure sensor 120 is located within the active cargo carrier mounting system 100 to sense vacuum pressure. The pressure sensor 120 is communicatively coupled to the microcontroller. The pressure sensor 120 may be a separate component located along the vacuum line, at a vacuum pump, within a vacuum cup, and/or at a tee fitting. Alternatively, or additionally, the pressure sensor 120 may be an integrated component of the vacuum pump.

The microcontroller, in an example embodiment, monitors the vacuum pressure generated by the vacuum pump(s). The microcontroller 108 is controllably coupled to the vacuum pump(s) to control the vacuum pump(s) to maintain a desired vacuum pressure in the vacuum line. Accordingly, the vacuum pressure within each of the plurality of vacuum cups 106 can be controlled to a desired pressure value. For example, the vacuum within the plurality of vacuum cups 106 and the vacuum line 114 will vary with vehicle elevation. In instances where the user drives the vehicle to a higher elevation, or to a lower elevation, the microcontroller 108 may operate the vacuum pump(s) to adjust and/or maintain the vacuum pressure to the desired target pressure value as the elevation of the vehicle changes during the trip. As another example, the vacuum pressure may be varied as a function of vehicle velocity. Here, a higher vacuum pressure may be generated at higher vehicle velocities.

The microcontroller 108 includes, or is coupled to, a wireless communication system that enables communication between the active cargo carrier mounting system 100 and the user's portable hand held electronic device, such as a smart phone, notebook, or the like. Alternatively, or additionally, the microcontroller 108 may be communicatively coupled to a control system of the vehicle. In a preferred embodiment, the user may use their portable hand held electronic device and/or the vehicle control system to operate and/or monitor performance of the active cargo carrier mounting system 100.

The battery 112 provides power for operation of the vacuum pump(s) and/or the microcontroller. In a preferred embodiment, a plurality of interchangeable batteries may be available to the user. For example, a first battery 112 may be used to operate the active cargo carrier mounting system 100 during a trip. A second battery 112 may be held in reserve, and/or may be charged using the vehicle's electric system.

In a preferred embodiment, the microcontroller 108 monitors battery power that is currently available from the battery. If battery power decreases below a threshold, a warning notification may be communicated from the microcontroller 108 to the portable hand held electronic device and/or the vehicle control system. In some embodiments, power management recommendation may be made to the user so that they can manage their trip. For example, if a low battery condition occurs, or if a low battery condition can be projected to occur in the near future, the user may halt their trip to replace the battery 112 and also perform other actions, such as stopping at a rest stop, eating at a restaurant, and/or filling up their vehicle with gas.

In some embodiments, the active cargo carrier mounting system 100 may be coupled to the electric system of the vehicle. For example, a power cord or the like may couple the active cargo carrier mounting system 100 and the vehicle electric power system.

FIG. 2 is a side view of an active cargo carrier mounting system 100 secured to a vehicle roof 104 top.

FIG. 3 is a partially transparent perspective view of an active cargo carrier mounting system 100. FIG. 4 is a drawing of a side view of an active cargo carrier mounting system 100 secured to a roof top of a vehicle. Here, the cargo carrier 102 is relatively large, wherein a leading edge of the cargo carrier 102 extends some distance beyond the roof line of the vehicle roof. Here, the leading vacuum cups 106 firmly secure the leading portion of the cargo carrier 102 to the vehicle roof.

In other embodiments, the cargo carrier 102 may be relatively small. The smaller active cargo carrier mounting system 100 may be releasably secured to the larger vehicle roof 104 at any suitable desired location. In practice, multiple cargo carriers (each with their own active cargo carrier mounting system 100) may be secured onto the vehicle roof. Alternatively, a single active cargo carrier mounting system 100 may be used to secure multiple cargo carriers. For example, two cargo carriers may be mounted side by side, or end to end, on the vehicle roof. The use of multiple cargo carriers may enable the user to sort the contents of each cargo carrier 102 in any desire manner. For example, one cargo carrier 102 might be used to carry water toys or scuba equipment, while the other cargo carrier 102 may be used to store dry clothes.

FIG. 5 is a drawing of a perspective view of an active cargo carrier mounting system 100 secured to a roof top of a vehicle. FIG. 6 is a partially transparent perspective front view of an active cargo carrier mounting system 100 secured to a roof top of the vehicle of FIG. 5 . FIG. 7 is perspective rear view of an active cargo carrier mounting system 100 secured to a roof top of the vehicle of FIG. 5 . FIG. 8 is a partially transparent perspective view of an active cargo carrier mounting system 100 secured to a roof top of the vehicle of FIG. 7 .

An unexpected advantage of embodiments of the active cargo carrier mounting system 100 is that a single product may be suitable for securing a particular cargo carrier 102 to many different vehicle models and brands. The advantage is even greater when the cargo carrier 102 is made of a semirigid material so that the active cargo carrier mounting system 100 can be secured to different vehicle roof 104 profiles.

Further, the number of and/or location of the plurality of vacuum cups 106 may be defined based on the known shape and profile of the vehicle roof, and/or based on the shape and size of the cargo carrier 102 that is based on the needs of the user, weight of the cargo load, vehicle speed, duration of trips, and/or geographic locations of travel. In some embodiments, the user may modify the number of and/or location of the vacuum cups being used to secure the active cargo carrier mounting system 100.

In some embodiments, two or more vacuum lines may be used to provide vacuum to selected vacuum cups. Using multiple vacuum lines improves reliability in the event that there is a failure of one of the vacuum lines. In a preferred embodiment, each vacuum cup 106 and/or tee fitting 116 includes an internal shut off valve that can isolate a failed vacuum cup 106 from the vacuum line 114 in the event of a failure. Further, a user notification may be sent by the microcontroller 108 to the user's portable hand held electronic device and/or the vehicle control system to warn the user of the failure. Accordingly, the user may pull off the road to resolve the vacuum line failure.

It should be emphasized that the above-described embodiments of the active cargo carrier mounting system 100 are merely possible examples of implementations of the invention.
